RSpec matchers for Protobuf.

require "rspec/protobuf"

subject { MyProtoMessage.new(msg: "hi") }

it { is_expected.to be_a_protobuf }

# check type
it { is_expected.to be_a_protobuf(MyProtoMessage) }

# check field values
it { is_expected.to be_a_protobuf(msg: "hi") }
it { is_expected.to be_a_protobuf(msg: /^h/) }

# composite matching
it { expect(result).to include(data: a_protobuf(MyProtoMessage, msg: starting_with("h"))) }
